Application filed February 10, 1913. Serial No. 747,398;

To all whom it may concern:

Be it known that I, DANIEL J. MURNANE, a citizen of the United States,residing at St; Louis, Missouri, have invented a certain new and usefulImprovement in Window Structures, of which the following is av fail,clear, and exact description, such as will'enable others skilled in theart to which it appertains to make and use the same.

This invention relates to store-fronts and show-window structures of thetype in which the outside glass clamping member consists of a piece ofhollow sheet metal molding that is arranged in engagement with the glassand with a forwardly pro ecting portion of the stationary frame in whichthe glass-is set.

The main object of my present invention is'to provide an inexpensivestructure of the character referred to which is so designed that theoutside glass-clamping member will remain in snug engagement with theglass and with the forwardly projecting portion of the stationaryglass-[supporting frame and thusinsure a tight joint between theseparts.

Another object is to provide a structure of the character described'thatcomprises a hollow sheet metal outside glass clamping member, fasteningdevices passing through the lower portion of said member atapproximately right anglesto the plane in which'th'e glass lies, andmeans for prevent ing said glass-clamping member frcm tilting or movinginto an angular position with relation to the glass and the stationaryframe when said fasteningdevices are tightened."

Another object is to provide a structure of the character just describedin which the means that prevents the glass-clamping member from tiltingcomprises a portion that reinforces and strengthens the hollow sheetmetal outside glass-clamping member.

Other objects and desirable features of my invention will be hereinafterpointed out.

Figure l is a perspective View of a window structureembodying myinvention; Fig. 2 is a front elevational view partly broken away oftheparts shown in Fig. '1, Fig-3 is a cross sectionalview'illustrat-ing' designates a stationary glasssupporting frame, Bdesignates a sheet of glass that is arranged therein, and C designatesthe outside glass-clamping member which presses the glass inwardly andholdsit in engagement with a shoulder or abutment 1 on the frame A. Saidframe isprovided with a forwardly projecting portion 2' on which theclamping member C bears, and means which preferably consists ofscrew-threaded fastening devices 3, are provided for securely connectingthe clamping member G to the frame A. The outside glass-clamping memberC consists of a piece of hollow sheet metal molding of any preferredcross sectional shape, and the fastening devices 3 pass transverselythrough the lower portion of said molding at approximately .right anglesto the vertical plane in which the glass lies. The clamping member Cherein shown is provided with a flat base portion 4 that bears upon theforwardly projecting portion of the frame A and an invertedchannel-shaped portion 5 whose inner leg hears against the front face ofthe glass, but I i it to be understood that my invennot limited to astructure having an S.-"l aul shape herein shown for the par ticulardesign of the clamping member C is immaterial so far asmy broad idea isconcerned.

It 1S necessary that the fastening devices 3 pass through the lowerportion of the clamping member C so that they will clear the glass, andin view of the fact that said fastening devices pass through theclamping member C at a. point below the neutral horizontal EIXlS'Of saidclamping member, there e glass-clamping member of the cross- ,baseflange 4: of the clamping member 0 is a tendency for the clamping memberC to cant or assume an angular position with relation to the glass andto the forwardly projecting portion 2 of the frame A when thefasteningdevices 3 are being tightened and thus prevent the portions 4and 5 of the member 0 from hearing evenly upon the frame A and the glassB, respectively. In other words, when the fastening devices 3 are beingtightened the heads of same bear upon the front face of the clampingmember C and exert such a great inward pulling force on the lowerportion of the clamping member C that the base portion 4: of said membertilts upwardly away from the frame A and the upper edge of the portion 5of said clamping member tilts outwardly away from the glass. This, ofcourse, destroys the tight joint between the clamping member and theglass and the frame, and it also causes the lower edge ofthe inner legof the inverted channel-shaped part 50f the clamping member C to exertundue pressure on the glass and very often results in breaking of theglass. In order to overcome this tendency of the outside clamping memberC to cant orvmove out of snug engagement with the glass and with theforwardly projecting portion 2 of the glass-supporting frame when thefastening devices 3 are tightened, I have provided the clamping member 0with means that cooperates with the fasten-- ing devices and with thebase portion 4 of said clamping member to prevent said base P01131011from tiltmg or moving upwardly away from its cooperating surface on thestationary frame A when the fastening devices pull the clamping member Cinwardly toward the glass. The means that I prefer touse for thispurpose consists of a reinforcing device D arranged inside of the hol-'low clamping member C and provided with a substantially L-shaped portionwhose ver-' tical leg 6 is provided with openings 7, preferablyelongated slots as shown in Fig. 2,

through which the fastening devices 3 pass,

the device D either consisting of one long member or a plurality ofshort members, spaced. apart at intervals throughout the length of theoutside clamping member. The L-shaped portion of the device D isarranged in the manner shown in Fig. 1, the horizontally-disposed partlying upon the and the vertical leg 6 projecting upwardly fromthe innerend of said base flange. In

view of the fact that the fastening devices 3 pass through the verticalleg of the device D said leg cooperates with the fastening devices 3 toeffectively prevent the base flange 4 of the clamping member C fromtilting upwardly when the fastening devices are tightened, theportion ofthe leg-6 that lies between the under side of the screws 3 and the baseflange 4: acting as a stop or abut ment that securely holds said baseflange in proper position. -Gonsequently, when the straight line andthus causethe portions 4 and 5 ofsaid member to ,remainin snugen-igagement with the frame and with the glass, respectively.

Thedevice D is preferably provided with curved portion 8 that projectsupwardly into the inverted channel-shaped part 5 of the clamping memberC and thus reinforces and strengthens said portion, thereby make ing itpracticableto form the outside-glass- 1 clamping member I Cfromcomparatively thin sheet metal.

Insteadof arranginga device'D inside; of;-

the clamping member C, as shown in-*-Fig. 1, V r

the base flange of the member Qcould be";

projecting tongue ,or tongues that would ,1: strike against the underside, of the fastening devices 3 and thus overcome, any tendency of themember C totiltwhen the fas- V j tening devices 3 are tightened, saidtongue or tongues eitherbeing formed integral'with 1 said base flange orformed onpra "separate, Y part 'QriVeted or secured in any othermaa; 1;;7

provided at its inner edge with an upwardly ner to the base flange .43of the outside glas s clamping member, as showninFig. 3. A structure ofthe character abovede-l scribed is inexpensive to manufacture, it can-jI be installed quickly and easily, land as it comprises a means thatprevents theloutside clampingfmember C from tilting when-it is. beingdrawnlintoengagement with the glass,- the liability .of breaking theglass by undue 1 i pressure of the clampingmember is reduced to aminimum, and a tight oint between the clamping member and the'gla-ssand-between the clampingmember .and' theforwardly pro ecting-portionofthe stationary frame A is always insured;

Instead of having the glassbear against I an abutment .1 on thestationary glass-sup;

porting frame, as shown? in Fig. 1, aniinsideg? clamping member E can bearranged be- ;i-

tween the glass; and the abutment l on the frame, as shownin Fig 4,, 5 d6 f ey drawings. herein shown is of novel 'design and'isso The insideclamping member constructed thatit cooperates with the glass to form agutter'for collecting the water that drains down the inner face 'of theglass, A As shown in Fig. A of thedrawings the in-' v sideglass-clamping member Ecomprises a 1 V vertically disposed portionlOarranged ,in

front of the abutment 1 on the frameqAQ; a i

and provided at its-upper edge with a for Y wardly projecting flange 11;The "flange 11.

inclines. downwardly slightly toward-the glass so as to form the bottomof agutter qwhose cooperating verticalwall is formed by the innerface'of the glass B. The front edge of the inclined flange 11 ispreferably provided with a depending lip 12 which bears against theinside face of the glass, and at intervals the lip 12 is pressedinwardly so as to form drain openings 16 through which the water escapesfrom said gutter, but I wish it to be understood that it is notessential that the drain openings be formed in this exact manner as theycould be formed in various other ways without departing from the spiritof my invention. The member E is preferably formed from sheet metal, andin order to impart the requisite strength and stiffness to same I employa number of clips 13 that bear against the rear side of the dependingflange 12, said clips being arranged in front of the vertically disposedportion 10 of the member E and being connected to the abutment 1 of theframe A by means of fastening de vices 1%. Each clip 13 is provided atits upper end with a forwardly projecting portion 15 having an upturnedflange that bears against the depending lip 12 on the member E, theclips 13 serving as rigid abutments which prevent the lip 12 fromyielding when the glass is pressed against same during the operation ofsetting'the glass. The water that drains through the openings 16 in thetop gutter previously described is collected by a bottom gutter arrangedbelow the bottom edge of the glass, as shown in Fig. t, said bottomgutter being preferably formed by the base portion 4 of the outsideclamping member C and an upwardly projecting flange 17 on the inner edgeof said base portion. In the form of my invention shown in Fig. at thebottom portion 4" of this lower gutter is provided with drain openings18 through which the water escapes, and in the form of my inventionshown in Fig. 6 drain openings 19 are formed in the front portion of theclamping member C adjacent the base portion t of same so that the watercan escape from the bottom gutter, as indicated by the arrows in Fig. 6.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
